This Tuna Ochazuke is my personal take on a Japanese comfort dish, layering warm rice with tuna, nori, green onions, sesame, and bonito flakes, with hot green tea poured over. It’s a simple, light, and umami-rich meal that’s quick to prepare.
I originally had a piece of salmon in the fridge that I planned to use for ochazuke. However, I ended up using it for my Teriyaki Salmon Bowl. Even so, I couldn’t stop thinking about making ochazuke.
Since I didn’t have time to get salmon again, I decided to make a simpler version using tuna, and it turned out to be exactly what I was craving.
If you enjoy simple meals, have little time in the kitchen, or often rely on food deliveries, this Tuna Ochazuke might be perfect for you. It uses just a handful of ingredients, and chances are you already have most of them in your pantry.
Most importantly, it is the kind of dish that quietly warms the soul, comforting, light, and effortlessly satisfying.
What is Chazuke or Ochazuke?
Ochazuke, also called chazuke, is a Japanese dish where hot green tea, dashi, or broth is poured over cooked rice and topped with ingredients such as fish, nori, sesame seeds, or pickles. The name literally means “tea over rice” (ocha = tea, zuke = soak). Originally a practical method to use leftover rice, ochazuke evolved into a versatile comfort dish.
In recent years, it has gained international attention, appreciated for its umami depth, simplicity, and ability to transform basic ingredients into a satisfying, soul-warming dish.

Tuna Ochazuke Ingredients
Cooked rice. Most ochazuke uses white rice. I use a mix of red and black rice for extra fiber and a nuttier taste. Any cooked rice works.
Canned tuna. Tuna in water or brine gives a cleaner taste, but fresh tuna works if you want a richer flavor.
Nori strips. Adds savory flavor.
Dashi powder. Gives the dish umami, making simple rice taste flavorful.
Green tea. Bagged tea is convenient, but loose-leaf tea gives better flavor. The hot tea softens the rice and carries the toppings’ taste.
Bonito flakes. Adds smoky flavor and a delicate texture that blends into the tea.
Green onion. Gives a fresh, slightly sharp taste that balances the tuna and broth.
Sesame seeds. Adds nutty flavor and a light crunch. About 1 teaspoon per serving.
To Make Tuna Ochazuke:
- Prepare the rice. Place 1 cup of warm cooked rice in a serving bowl. Use white rice or a mix of red and black rice for extra fiber.
- Add the tuna. Top the rice with ½ cup canned tuna (drained). Fresh tuna works if you prefer.
- Layer the toppings. Sprinkle nori strips, 1–2 tablespoons chopped green onion, 1 tablespoon bonito flakes, and 1 teaspoon sesame seeds over the rice.
- Season with dashi. Lightly sprinkle ½ teaspoon dashi powder over the toppings to enhance umami flavor.
- Pour the tea. Slowly pour 1 cup hot green tea over the rice and toppings. Bagged tea is convenient; loose-leaf tea gives cleaner flavor.
- Serve immediately. Mix lightly if you like, then enjoy your warm, savory, and comforting Tuna Ochazuke.
